Excerpt from Water-Works: For Small Cities and Towns It is unnecessary here to give instructions as to the method of making the stadia survey, but a few notes on the use of a sketchboard may be appropriate, as the published information on the subject is meager and not readily secured. The sketchboard is merely a portable drawing-board on which the transit and stadia notes are plotted in the field as fast as practicable. These notes furnish the location and elevation of all the leading features of the tract surveyed, and it is an easy matter for a draughtsman to sketch in the intervening contour lines by eye. One of the best sketchboards known to the writer was designed by A. R. Paddock, and is described in "The Engineering Record" for October 31, 1891, and February 6, 1892. The top is a wooden frame, into which fit four small wooden squares. The top of each square is covered with drawing-paper, which is turned over the edges and fastened to the lower surface. When the four squares covered in this way are placed in the frame a uniform paper surface of about 310 square inches is furnished for sketching. Whenever the plotting approaches one edge of the board, as the east, the two eastern sections are transferred to the west edge and two fresh ones put in their place. The field notes were plotted on these tables in two ways. Some were laid off by using the magnetic bearings and marking off the points with a card protractor having a scale on one edge, while others were fixed by using a simple alidade consisting of a metallic triangular scale with a pair of sighting wires attached. The cost of a table of this sort was about $11. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
